The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the way for Jaconé, with some real standout moments for the experienced crew.

The overall pattern sees a strong pulse of S groundswell arriving mid-week, with a very long-period 15-second swell on Wednesday the 26th afternoon. That’s a serious amount of energy – the combined energy hits 3121 – but that’s a big boy's wave. The morning session on the 26th is the real gem though: glassy conditions with a light E wind at 3 mph, and a 7 ft S swell at 12 seconds (2101 energy). That’s clean, powerful, and lined up. The water temp is about average for this time of year, so no surprises there.

The standout window is Wednesday morning the 26th. Jaconé will be firing with that 7 ft S swell, period around 12 seconds, and glassy conditions. It’s a consistent spot, exposed to the south swell, but keep in mind it can get crowded. For the experienced surfer, this is the pick of the forecast.

As we move into Thursday the 27th, we’ve got a 8 ft S swell with a 14-second period and a clean offshore NE wind at 9 mph in the morning. That’s another excellent session for the confident surfer, though the energy is still high at 2209. The wind holds offshore through the morning, so the waves will be well-shaped.

Friday the 28th drops down a notch – 4 ft S swell in the morning, cleaner with a light offshore breeze, but the period shortens to 12 seconds. Still good fun, but not the power of the earlier days.

The weekend brings a shift in swell direction. Saturday the 29th and Sunday the 30th see ENE swell, shorter period around 8 seconds, and lighter winds. The morning of the 30th has a 7 ft ENE swell with a light offshore NNE breeze – that’s a clean, fun option for intermediates, though the shorter period means it won’t have the same punch.

Monday the 31st morning sees a return to a better ENE groundswell at 7 ft, 9-second period, with a clean offshore NE wind. Good energy (865) and good shape.

The first week of September gets a bit messy. Tuesday the 1st is a write-off with cross-onshore winds and a weak, short-period SW swell. Wednesday the 2nd has a brief window with a light cross-offshore wind and a small SSW swell, but the afternoon turns onshore and brings a 7 ft SSW swell at 12 seconds – that’s a lot of energy (1345) but with onshore wind, it’ll be a bumpy mess.

The second week settles down. Thursday the 3rd and Friday the 4th have some S swell, but winds are variable. The 4th morning looks promising with a 5 ft S swell at 10 seconds and a gentle offshore ENE breeze – clean and surfable.

Saturday the 5th morning is a top call: 5 ft S swell at 11 seconds, with a moderate offshore NE wind at 12 mph. Clean, punchy, and good energy (618). The arvo gets blown out with a fresh 19 mph E breeze, so get on it early.

Sunday the 6th morning is a write-off due to cross-offshore winds, but the afternoon goes glassy with a small 3 ft S swell. Worth a paddle for a slow, clean session.

The final part of the forecast sees a new pulse of ENE swell arriving on Tuesday the 8th morning, with a 6 ft ENE swell (short period, 7 seconds) and clean cross-offshore wind. Nothing special, but rideable. Then Thursday the 10th morning brings a solid finish: a 7 ft S swell at 11 seconds (1378 energy) with a light offshore NE wind. That’s clean, powerful, and for the experienced only.

There’s a few days in the middle of the first week – Tuesday the 1st and Wednesday the 2nd – where the surf is poor, but the rest of the window has plenty of action. For the best of the best, lock in Wednesday the 26th morning. That’s the one.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
